CD8+ T cells stimulated by exosomes derived from RenCa cells mediate specific immune responses through the FasL/Fas signaling pathway and, combined with GM‑CSF and IL‑12, enhance the anti‑renal cortical adenocarcinoma effect. Oncol Rep. 2019 Jun 20;: Authors: Xu HY, Li N, Yao N, Xu XF, Wang HX, Liu XY, Zhang Y Abstract A satisfactory cure rate for renal cell carcinoma (RCC) is difficult to achieve through traditional immunotherapy. RCC has a relatively high spontaneous regression rate due to tumor immune escape. However, tumor‑derived exosomes (TEXs), which effectively carry tumor‑associated antigens (TAAs) and trigger stronger antigen‑specific tumor immunity against autologous tumors than against other tumors, have been widely viewed as attractive potential vaccines for tumor treatment, although improvements are needed. Therefore, in our study, we determined whether RenCa cell‑derived exosome (RDE)‑stimulated CD8+ T cells exert a stronger specific cytotoxic effect on autologous tumor cells than on other types of tumor cells through the Fas ligand (FasL)/Fas signaling pathway, and whether the combination of RDE‑stimulated CD8+ T cells with GM‑CSF and IL‑12 enhances the anticancer effect. The results showed that RDEs were isolated, as expected, and promoted an increased percentage of CD8+/CD4+ T cells. RDE‑stimulated CD8+ T cells also more effectively facilitated cytotoxicity against RenCa cells when combined with GM‑CSF and ...

CONCLUSION: DS-GPA seems to be a reliable tool to classify patients with brain metastases treated with SRS into prognostic subgroups. However, we found some aberrations from predicted median survival times, which may be due to specific characteristics of the populations of patients treated with SRS versus other patients.

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (www.oncomine.org), a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...

In addition to their antimicrobial activities, they possess other functions; e.g., cell activation, proliferation, regulation of cytokine/chemokine production, migration, diffe...

Conclusions: This meta-analysis demonstrated that CD44 overexpression might be an unfavorable prognostic factor for CRC patients and could be used to predict poor differentiation, lymph node metastasis and distant metastasis. Introduction Although therapies for colorectal cancer (CRC) has improved in recent years, colorectal cancer is still the third most common cause of cancer related death worldwide (1). Metastasis are observed in 25% of patients at initial diagnosis and approximately 50% of patients will develop metastasis (2). Presently, the outcome prediction and the therapy schedule determination of CRC patie...

In this study, the lung adenocarcinoma patients and granuloma patients were treated as positive samples and negative samples, respectively. We used weighted accuracy to evaluate the RIPPER prediction performance, i.e., the average of the accuracies of positive samples and negative samples. Results The Discriminative MicroRNAs Between Lung Adenocarcinoma and Granuloma Patients in Whole Plasma, EV, and EV-Free Plasma The miRNA expression profiles of lung adenocarcinoma and granuloma patients in whole plasma, EV and EV-free plasma were analyzed separately. In whole plasma, the top 10 discriminative miRNAs were hsa-miR-223-...

Despite advances in the development of strategies for treating EC, prognosis of the disease remains unsatisfactory, especially for advanced EC. The aim of this study was to identify novel genes that can be used as potential biomarkers for identifying the prognosis of EC and to construct a novel risk stratification using these genes. Me...

This study aimed to investigate whether combining anti-PD-L1 Atezolizumab with BEV may have a synergistic effect and enhance the efficacy of both treatments in cisplatin resistant epithelial ovarian cancer (CREOC). We retrospectively analyzed 124 epithelial ovarian cancer (EOC) patients from Gynecologic Oncology Department of Tianjin Cancer Hospital between January 2013 and June 2018, who all were diagnosed with cisplatin resistance due to progressing

In this study, we confirm our initial findings from the proteomic screen and demonstrate that LASP1 can interact with both eIF4A and eIF4B. Importantly, the LASP1-eIF4A and LASP1-eIF4B interaction is shown to be CXCL12-dependent. In addition, the ability of CXCR4 to impact the phosphorylation of eIF4F regulatory proteins is provided. Taken together, we hypothesize that activation of CXCR4 can promote eIF4F complex formation and activity through LASP1 and cell signaling. As a result, the translation of oncogenic proteins is promoted thereby mediating an invasive and metastatic phenotype commonly associated with CXCR4. Mate...

In this study, we evaluated whether the combination of focused ultrasound (FUS) and microbubbles can improve adoptively NK-92MI cell infiltration into ovarian tumors through biodistribution, immunofluorescence, and flow cytometry. The treatment effects of using this strategy twice a week were explored. The potential molecular mechanism of FUS assisting NK cell therapy was also initially explored through evaluating the expression of ICAM1 and CX3CL1 by qRT-PCR. Our results indicated that FUS and microbubbles can improve NK-92MI cells’ infiltration into tumors, and the combination of FUS and NK-92MI cells had a better ...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...
